macOS. It’s why there’s nothing else like a Mac.

macOS is the operating system that powers every Mac. It lets you do things you simply can’t with other computers. That’s because it’s designed specifically for the hardware it runs on — and vice versa. macOS comes with an entire suite of beautifully designed apps. It works hand in hand with iCloud to keep photos, documents, and other stuff up to date on all your devices. It makes your Mac work like magic with your iPhone. And it’s been built from the ground up with privacy and security in mind.

Easy to Use
When it’s simple to do everything, you can do anything.

On a Mac, everything is designed to work just the way you expect it to — from operating it with simple, intuitive gestures to asking Siri to find a file to having your apps automatically update themselves. Whatever you set out to do on a Mac, there’s much less to learn and that much more to accomplish.

Siri helps you get things done just by using your voice. It also helps you get more things done at the same time. So you can finish your document while asking Siri to tell your coworker that it’s on the way. Looking for the presentation you worked on last week? Just ask Siri.1 And with Apple Music, Siri can be your personal DJ and recommend music based on your tastes, and tell you more about songs, albums, and artists.2

The Finder lets you easily browse and organize the files on your Mac — and those stored in iCloud Drive.

Spotlight helps you quickly and effortlessly find what you want, like documents on your Mac, movie showtimes, and flight departure and arrival times. Just type a few keystrokes in the Spotlight search field and autocomplete immediately shows you relevant results.3

A simple two-finger swipe brings up Notification Center — the same one you use on iPhone — where you can see all the alerts that have come in recently. It’s also where you’ll find your Today view, which you can customize with helpful widgets or handy information pinned from Siri searches.

Continuity
All your devices.One seamless experience.

Your Mac works with your other Apple devices in ways no other computer can. If you get a call on your iPhone, you can take it on your Mac. You can copy text or an image from one device and paste it into another with standard copy and paste commands. You can even unlock your Mac just by walking up to it wearing your Apple Watch. No password typing required.

Built-in Apps
Apps as powerful and elegant as your Mac. Because they’re designed for it.

With every Mac, you get a collection of powerful apps. They’re the same apps you use on your iPhone or iPad, so they’ll feel instantly familiar. They all work with iCloud, so your schedule, contacts, and notes are always up to date everywhere. And because they’re native apps — not web apps in a browser — they take full advantage of the power of your Mac to deliver the fastest possible performance and more robust features.

Creativity. Organize, edit, and share a lifetime’s worth of photos and videos, and rediscover your favorite memories. Transform home videos into unforgettable movies or quickly share clips with your favorite people. Create music like the pros with a huge collection of sounds, instruments, amps, and a lineup of virtual session drummers and percussionists perfectly suited to play along with your song.

Productivity. Create beautiful documents with stunning simplicity. Visualize your data precisely and persuasively in spreadsheets with images, text, and shapes. Make stage-worthy presentations using powerful graphics tools and dazzling cinematic effects to bring your ideas to life. And collaborate with friends and coworkers in real time — whether they’re across town or across the globe.

Communication. Easily manage all of your email accounts in one simple, powerful app that works with email services like iCloud, Gmail, Yahoo, AOL, and Microsoft Exchange. Send unlimited messages to anyone on any Apple device, using the same Messages app on your Mac as you do on your iPhone. And make unlimited high-quality video and audio calls right from your Mac with FaceTime.

Keep all your contact info up to date on all your devices, and easily import numbers, addresses, and photos from Facebook, LinkedIn, Google, and even Microsoft Exchange. And keep track of little and big things with notes that can include links, photos, map locations, tables, and more.

Internet. Surf the web on the fastest, most energy-efficient browser,4 with built-in privacy features that keep you in control of your information. Map out new destinations from your desktop, with gorgeous 3D city views like Flyover, point-to-point directions, and comprehensive transit directions. And with Spotlight, instantly search your entire Mac or get results from the Internet in just a few keystrokes.

Media. Find the latest apps and extensions for your Mac, right on your Mac. Enjoy the music, movies, and TV shows you already have on your beautiful Retina display, or discover soon-to-be favorites. And take advantage of the world-class bookstore built into your Mac, where you can peruse the latest titles from your desktop.

Every Apple app uses iCloud — it’s the magic behind the seamless experience you have with all your Apple devices. So you always have your photos, videos, documents, email, notes, contacts, calendars, and more on whatever device you’re using. And any file you store in iCloud Drive can be shared with friends, family, and colleagues just by sending them a link. iCloud Drive also lets you access files from your Mac desktop and Documents folder on any iOS device. It’s all done automatically. Just like that.5

Technology
Advanced to the core.

macOS features powerful core technologies engineered for the most important functions of your Mac. The Apple File System manages all the data on your Mac, bringing a new level of security and responsiveness to flash-based systems. High Efficiency Video Coding (HEVC) introduces a new standard for video compression, making movie files up to 40 percent smaller and 4K streaming video faster.6 Metal 2 powers the graphics behind every pixel, making your gaming experience more visually breathtaking and fun. And support for virtual reality lets developers create immersive worlds for you to step into.7

Privacy and Security
We believe your data belongs to you. Period.

Everything you do with your Mac is protected by strong privacy and security features. That’s because we build data security into everything we make, right from the start.

Privacy. You trust our products with your most personal information, and we believe very strongly that you should be in complete control of it. That’s why we respect your privacy and protect it with strong encryption and strict policies that govern how all data is handled.

Security. macOS is engineered with advanced technologies that are constantly working together to keep your Mac and the information on it safe. Gatekeeper makes it safer to download and install apps from the web. The Apple File System further safeguards your data with built-in encryption, crash-safe protections, and simplified data backup on the go.

Compatibility
Need to work with Windows? Mac does that, too.

With macOS, it’s easy to transfer your files, photos, and other data from a Windows PC to your Mac. Work with popular file types such as JPEG, MP3, and PDF, as well as Microsoft Word, Excel, and PowerPoint documents. And, of course, you can run Microsoft Office natively on a Mac. If you want, you can even run Windows on your Mac.8

Accessibility
We make sure that everyone is able to use a Mac.

macOS comes standard with a wide range of assistive technologies that help people with disabilities experience what the Mac has to offer, providing many features you won’t find in other operating systems. These include VoiceOver, FaceTime,9 Switch Control, and text to speech, all designed to help anyone get more out of Mac.

macOS High Sierra
Your Mac. Elevated.
